I have at current the, calculated member
create member [017SKY_DATAWAREHOUSE].[Measures].[ConversionTest]
as
([Measures].[Lead Count]
,[Origin].[Origin].[Origin Sale Type Description].&[Sky].&[Direct Referral]
,[Misc Flag].[Sale Flag].&[True])
/
([Measures].[Lead Count]
,[Origin].[Origin].[Origin Sale Type Description].&[Sky].&[Direct Referral]),
format_string = "percent"
However I need to numerator of this member to act over one date dimension, and the denominator to act over another date dimension, that is if I cut this Calculated member by date dimension A I need the numerator to be cut by data dimension B.
How do I achieve this?
The function LinkMember is the suitable to do this.
(
[Measures].[Lead Count]
,[Origin].[Origin].[Origin Sale Type Description].&[Sky].&[Direct Referral]
LinkMember([Date].[Date].[July 1, 2002], [Date].[Calendar])

I was able to calculate PY Total for Selected Time Dimension's Attributes in individual Hierarchy but cannot figure out how to make it work for both Time Dimension Hierarchies with single calculated measure.
I had to USE Dynamic SET to populate Days and use AGGREGATE on the SET as follows -
CREATE DYNAMIC SET CURRENTCUBE.[Days]
AS {EXISTING [Time].[Time].[Day]};
CREATE MEMBER CURRENTCUBE.[Measures].[PY Sales Selected]
AS AGGREGATE(
GENERATE(EXISTING [Days],
{PARALLELPERIOD([Time].[Time].[Year],1,[Time].[Time].CurrentMember)}
),
[Measures].[Sales]
),
FORMAT_STRING = "#,#",
VISIBLE = 1
----
CREATE DYNAMIC SET CURRENTCUBE.[Days]
AS {EXISTING [Time].[Current].[Curr Day Flag]};
CREATE MEMBER CURRENTCUBE.[Measures].[PY Sales Selected]
AS AGGREGATE(
GENERATE(EXISTING [Days],
{PARALLELPERIOD([Time].[Current].[Curr Year Flag],1,[Time].[Current].CurrentMember)}
),
[Measures].[Sales]
),
FORMAT_STRING = "#,#",
VISIBLE = 1
Both calculations work individually but I would like to combine them so that I could just have one Calculated Measure [Measures].[PY Sales Selected].
We have following Time dimension structure -
I would appreciate any help!!
I Tried to create a calculated measure inn my SSAS cube with complex filters as the following:
([Measures].[Amount],[Scenarios].[Scenario Key].&[1],[AccountType],[AccountType].[Account Type].&[Bank],[AccountType].[Account Type].&[Cash],[AccountType].[Account Type].&[NotesReceivable],[JE Type].[JE Type].&[CI],[JE Type].[JE Type].&[NR])
I want to Get the summation of amount value which has:
Scenario Key = 1
Account Type IN ("Bank","Cash","NotesReceivable")
JE Type IN ("CI","NR")
But i Get this measure as Null So can any one can help to solve this?
It's not working because you are doing an intersection of the same dimension hierarchy:
[AccountType].[Account Type].&[Bank],[AccountType].[Account Type].&[Cash]
means in MDX: Account Type = Bank AND Account Type = Cash at the same time.
Just use set of members and SUM function.
Try this one:
SUM(
{[AccountType].[Account Type].&[Bank]
,[AccountType].[Account Type].&[Cash]
,[AccountType].[Account Type].&[NotesReceivable]}
*
{[JE Type].[JE Type].&[CI]
,[JE Type].[JE Type].&[NR]}
,([Scenarios].[Scenario Key].&[1],[Measures].[Amount]))
Explanation:
SUM - aggregate function
Dimension1 filter * Dimension2 filter - gave all combinations
(Dimension3,measure) - filters out single-selected dimensions
I have a cube with 4 dimensions and I have a measure called Transaction Count. Now I want to calculate the Percentage across all the dimensions for that above measure.
I also have a dimension called Cars. I have the count across all the Cars and now I have defined a calculated measure for calculating the Percentage of each car from the total number of transactions. But it will work only for that particular dimension.
How I can create a single percentage calculated measure which can be used across all the dimensions?
MDX for the calculated measure: (which is working for only Carmake dimension)
CASE
WHEN ISEMPTY( [MEASURES].[Trans COUNT] )
THEN 0
ELSE ([Dim Car Make].[Hierarchy].CURRENTMEMBER,
[MEASURES].[FACT COLORPERFORMANCE COUNT])/
( [DIM CAR MAKE].[CARMAKE].[(ALL)].[ALL],
[MEASURES].[Trans COUNT])
END
I already have a Trancount(1000) measure. Now I need to create a calculated measure Freq % which should be calculated across all the dimensions.
Screenshot -> http://i.stack.imgur.com/iuaQO.jpg (need 10 rep for posting images)
Table 1 in screenshot - you drag and drop the carmake dimension, then both Tran Count and Freq% should be calculated as per CarMake breakdown.
Table 2 in screenshot - you remove CarMake and drag Quality, then both Tran Count and Freq% should be calculated as per Quality breakdown.
Table 3 in screenshot - you remove Quality and drag Brand, then both Tran Count and Freq% should be calculated as per brand breakdown.
The best way i found is using AXIS() to dynamically get the currently used dimension.
with
member Member_Lvl as AXIS(0).item(0).level.ordinal --get the level for next calc
member All_Member as sum(ancestor(axis(0).item(0).hierarchy.currentMember,<yourMeasure>),Member_Lvl )
member Percent_of_All as sum(axis(0).item(0).hierarchy.currentMember,<yourMeasure>) / All_Member
select <Your Dim > on 0, {<Your Measure>, Percent_of_All} on 1
from <Your Cueb>
NOTICE: replace the SUM function on the calculations if you need other aggregation.
In my product dimension, I have an attribute called CustomerRating which is a string. Possible values are "1", "2", "3", and "4".
I want to turn this attribute into a Measure that averages ratings for collections of products.
with member [Measures].[Product Rating] as
( [Product].[Project Name].CurrentMember.Properties("CustomerRating"))
select [Measures].[Product Rating] on columns
from [MyCube]
This query produces an error - I suspect because I'm dealing with a string.
How do I turn customer rating into a measure that is an average rather than a sum?
The best approach would be to add an int column to the source table of the dimension, maybe just as a named calculation in the DSV. Then you would add a measure group on the dimension table, and define a measure rating_sum that sums this column, and a count measure in this measure group.
Then define a calculated measure as rating_sum / count.
If everything works, make the two measures rating_sum and count invisible.
Not tested but I'm wondering if this errors?

MEMBER [Measures].[Product Rating] AS
CInt([Product].[Project Name].CurrentMember.Properties("CustomerRating"))

I am trying to calculate percentile (for example 90th percentile point of my measure) in a cube and I think I am almost there. The problem I am facing is, I am able to return the row number of the 90th percentile, but do not know how to get my measure.
With
Member [Measures].[cnt] as
Count(NonEmpty(
-- dimensions to find percentile on (the same should be repeated again
[Calendar].[Hierarchy].members *
[Region Dim].[Region].members *
[Product Dim].[Product].members
,
-- add the measure to group
[Measures].[Profit]))
-- define percentile
Member [Measures].[Percentile] as 90
Member [Measures].[PercentileInt] as Int((([Measures].[cnt]) * [Measures].[Percentile]) / 100)
**-- this part finds the tuple from the set based on the index of the percentile point and I am using the item(index) to get the necessary info from tuple and I am unable to get the measure part
Member [Measures].[PercentileLo] as
(
Order(
NonEmpty(
[Calendar].[Hierarchy].members *
[Region Dim].[Region].members *
[Product Dim].[Product].members,
[Measures].[Profit]),
[Measures].[Profit].Value, BDESC)).Item([Measures].[PercentileInt]).Item(3)**
select
{
[Measures].[cnt],
[Measures].[Percentile],[Measures].[PercentileInt],
[Measures].[PercentileLo],
[Measures].[Profit]
}

I think there must a way to get measure of a tuple found through index of a set. Please help, let me know if you need any more information. Thanks!
You should extract the tuple at position [Measures].[PercentileInt] from your set and add the measure to it to build a tuple of four elements. Then you want to return its value as the measure PercentileLo, i. e. define
Member [Measures].[PercentileLo] as
(
[Measures].[Profit],
Order(
NonEmpty(
[Calendar].[Hierarchy].members *
[Region Dim].[Region].members *
[Product Dim].[Product].members,
[Measures].[Profit]),
[Measures].[Profit], BDESC)).Item([Measures].[PercentileInt])
)
The way you implemented it, you tried to extract the fourth (as Item() starts counting from zero) item from a tuple containing only three elements. Your ordered set only has three hierarchies.
Just another unrelated remark: I think you should avoid using complete hierarchies for [Calendar].[Hierarchy].members, [Region Dim].[Region].members, and [Product Dim].[Product].members. Your code looks like you are including all levels (including the all member) in the calculation. But I do not know the structure and names of your cube, hence I may be wrong with this.
An alternate method could be to find the median of the last 20% of the records in the table. I've used this combination of functions to find the 75th percentile. By dividing the record count by 5, you can use the TopCount function to return a set of tuples that make up 20% of the whole table sorted in descending order by your target measure. The median function should then land you at the correct 90th percentile value without having to find the record's coordinates. In my own use, I use the same measure for the last parameter in both the Median and TopCount functions.
Here's my code:
WITH MEMBER Measures.[90th Percentile] AS MEDIAN(
TOPCOUNT(
[set definition]
,Measures.[Fact Table Record Count] / 5
,Measures.[Value by which to sort the set so the first 20% of records are chosen]
)
,Measures.[Value from which the median should be determined]
)
Based on what you've supplied in your problem definition, I would expect your code to look something like this:
WITH MEMBER Measures.[90th Percentile] AS MEDIAN(
TOPCOUNT(
{
[Calendar].[Hierarchy].members *
[Region Dim].[Region].members *
[Product Dim].[Product].members
}
,Measures.[Fact Table Record Count] / 5
,[Measures].[Profit]
)
,[Measures].[Profit]
)
